No CVSS score has been assigned to GHSA-v45m-2wcp-gg98 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-v45m-2wcp-gg98?

GHSA-v45m-2wcp-gg98 affects the following packages: bin-links (npm). Ecosystems affected: npm.

How do I fix GHSA-v45m-2wcp-gg98?

Update bin-links to 1.1.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v45m-2wcp-gg98 is resolved across your whole dependency graph.

How do I detect GHSA-v45m-2wcp-gg98 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bin-links, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-v45m-2wcp-gg98 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is GHSA-v45m-2wcp-gg98 actively exploited in the wild?

No public exploit code has been indexed for GHSA-v45m-2wcp-gg98 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

Versions of bin-links prior to 1.1.6 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent globally-installed binaries to be overwritten by other package installs. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the first binary. This behavior is still allowed in local installations.

Recommendation

Upgrade to version 1.1.6 or later.
